What are the Installation Requirements for your Aluzinc Steel Coil Roofing?

The most known method used to install the Aluzinc Steel Coil roof system is the standing roof seam system (SSRS).

According to this system, an aluminum and zinc coat are joined together by using the concealed fasteners at their sides fitted with a wooden or metallic structure.

For the first-time installation, Aluzinc Steel Coil panels are fitted to the purlin directly by using clips or fasteners and panels are on a substructure to form crimps or splinters on the layers of sheet.

For reconstruction use, panels are positioned on the infrastructure one by one attached to the roof design to provide sufficient drainage.

A slope of ½ 12 is allowed, if the slope is not made the rainwater will be stuck on the roofing, As a result, corrosion occurs.

Immediately after the installation, all the installation debris, like rivet stems and others must be cleaned. The rusting scraps can produce corrosion and decrease the stipulated life of the sheets.

What is the Difference between Zincalume and Aluzinc Steel Coil?

There is no difference between a zincalume and Aluzinc Steel Coil. The material and quality of both are the same.
